JOHN D. PHYFE AND JOHN D. PERRINE, OF NEW YORK, N. Y.

Letters Patent No. 114,037, dated April 25, 1871,

IMPROVEMENT IN SHUTTER-FASTENERS.

The Schedule referred to in these Letters Patent and making part of the lame.

, We, Joan D. PHYFE and JOHN D. PERRINE, of New York city and State'of New York, have invented certain Improvements in a Window-Blind and Shutter-Fastener, of which the following is a specification.

Nature and Objects of the Invention.

Our invention consists in combining and arranging the semi-cylindrical parts of the case with recesses in such a manner as' to require no rivets for the hooks, as hereinafter claimed.

Figure A represents the external view, showing the hooks A and B in vertical position, and the extension into cylinder, shown by .dotted lines.

Figure B represents the external view, showing the hooks in horizontal position and the shape of cylinder.. 1

Figure 0 shows the view of the end of cylinder on the side of book A and cut opening for the same. Figure D shows the endv of the cylinder on the side of hook B.

Figure E shows the section of the cylinder when taken apart, and the situation of hooks A and B inside of the vertical line.

Hooks A and B are perfectly independent of each other, which is shown by Fig. "E.

. Hook B is the inside or window-sill hook.

Hook, A, outside or wall-hook.

Both of these hooks are guided and fastened by a circular out inside of channel of cylinder corresponding to shape, and enabling them to have free movements without losing their proper places.

When the blind is closed and hook B has been fastened to the window-sill the outside hook A cannot operate on the inside' hook B by lifting the same, therefore the blind or shutter can only he opened from the inside. Contrary hook B will lift hook A when opened and fastened to the wall.

Claim.

What we claim as our invention is-- As an article of manufacture, the shutter-fastener composed of the longitudinal sectional parts, one carrying the face-plate, as shown, and the two secured by a screw-nut, the two books having projections working in recesses in the sides of the sectional case, and hence not requiring rivets, all as and for the purpose set forth.
